There are dates taught in history classes many Americans will always remember. December 7, 1941, is "a date that will live in infamy," as that day marks an unprovoked attack on Pearl Harbor. June 6, 1944, saw U.S. troops landing at Normandy and beginning the actions that resulted in the freeing of the continent of Europe from Nazi tyranny. November 22, 1963, was the day President Kennedy was shot, and "the day the music died;" and on April 4, 1968, in Memphis, Dr Martin Luther King, Jr was assassinated.

But for those of us of this generation, September 11, 2001, is a date we will always remember.

It has been ten years since the attacks on the World Trade Center buildings in New York, the Pentagon in Washington, DC, and the crash of a plane in Shanksville, Pa., which had as its target either the White House or the Capitol. Many of us remember exactly where we were on that Tuesday morning, and we remember what we were doing when the attacks occurred. Some of us had friends among the nearly 3,000 victims in those buildings, who were mostly American but who also represented citizens of over 70 different countries.

This was more than an attack on our country. It was an attack on liberty, human dignity, and shared security.

On this 10th anniversary, I would ask all the Soldiers, Civilians, and Family Members of US Army in Europe to dedicate time for silence and remembrance, as a tribute to the victims of the 9-11 attack. I would also ask you to remember those Soldiers " and all those who strive to defend liberty and the dignity of mankind -- who have dutifully served their country in the aftermath of those attacks, and those who have made the ultimate sacrifice in the ten years since our country was threatened by violent extremism.
